The Commission may, in its discretion, make such investigations as it deems necessary to determine whether any person has violated, is violating, or is about to violate any provision of this chapter, the rules or regulations thereunder, the rules of a national securities exchange or registered securities association of which such person is a member or a person associated, or, as to any act or practice, or omission to act, while associated with a member, formerly associated with a member, the rules of a registered clearing agency in which such person is a participant, or, as to any act or practice, or omission to act, while a participant, was a participant, the rules of the Public Company Accounting Oversight Board, of which such person is a registered public accounting firm, a person associated with such a firm, or, as to any act, practice, or omission to act, while associated with such firm, a person formerly associated with such a firm, or the rules of the Municipal Securities Rulemaking Board, and may require or permit any person to file with it a statement in writing, under oath or otherwise as the Commission shall determine, as to all the facts and circumstances concerning the matter to be investigated.

On request from a foreign securities authority, the Commission may provide assistance in accordance with this paragraph if the requesting authority states that the requesting authority is conducting an investigation which it deems necessary to determine whether any person has violated, is violating, or is about to violate any laws or rules relating to securities matters that the requesting authority administers or enforces. The Commission may, in its discretion, conduct such investigation as the Commission deems necessary to collect information and evidence pertinent to the request for assistance. Such assistance may be provided without regard to whether the facts stated in the request would also constitute a violation of the laws of the United States. In deciding whether to provide such assistance, the Commission shall consider whether (A) the requesting authority has agreed to provide reciprocal assistance in securities matters to the Commission; and (B) compliance with the request would prejudice the public interest of the United States.
